M9-14 Status

status: done task: Curve、Grease Pencil、Paint 三编辑域故障恢复闭环 updated: 2026-08-16 America/New_York

Scope

web/protocol/editing-domain-recovery.ts freezes one schema-v1 evidence shape for the three domains. Each report must prove Main identity, Worker generation, OOM fault mapping/cleanup, WebGL2 resource release/reinitialization, and a visible small-scene recovery. Save/reopen may reset the logical Main revision; the content identity SHA-256 remains the authoritative recovery check.

Evidence

Curve fixture: tests/files/web/nonmesh_scene.blend, SHA-256 ae8ef85d606aa120ce6b7611fc03407fd80bb60311e94a6ef73f6384d0b6c8b4.
Grease Pencil fixture: tests/files/web/modifier_grease_pencil_scene.blend, SHA-256 3a8525077807f9178dac3a5ba84b524e5f8e80874b15c54e2a6658ecb80315a3.
Paint fixture: tests/files/web/attribute_scene.blend, SHA-256 12fa75bb79f8c38e660d3d2a8fc9cc16dd3df4fc9208b0e2ad94fb1f8aa68f71.

Recovery boundaries

Worker restart uses a fresh WebEngineClient/Worker and reopens the saved bytes; stable domain identity is required, while revision reset on a newly serialized .blend is accepted and recorded.
OOM uses the token-isolated GPU_GEOMETRY_UPLOAD fault point. A tracked texture lease is released before close; the matching error is GPU_GEOMETRY_BUDGET_EXCEEDED, with zero live temporary resources.
GPU release disposes geometry, material and renderer once, then creates a fresh WebGL2 renderer and requires non-zero pixels for the same domain probe.
Small-scene recovery requires the reopened data IDs, identity hash, object count and visible pixels to match the committed baseline.

Rollback

Remove the M9-14 protocol/runner/tests/golden and package script together. Existing Curve, Grease Pencil and Paint writers remain unchanged; no persisted schema or release metadata migration is required.
